Hello,
I have configured openvpn server to give IP to clients in a specific range. My virtual network is /24 and the pool size is 59.
ifconfig 10.0.0.1 10.0.0.2
ifconfig-pool 10.0.0.13 10.0.0.254
But this is not enough recently and i want to increase the pool size. But can't just use netmask parameter with ifconfig-pool, because i am using in tun type.
The question is how can i increase the pool size ? I set the virtual netwrok /16 but can't increase the pool size. I want to arrange pool range myself because some users have static IPs.
All the configuration is,
ca /etc/ca/ca.crt
cert /usr/local/etc/openvpn/keys/server.crt
key /usr/local/etc/openvpn/keys/server.key
dh /usr/local/etc/openvpn/keys/dh.pem
cipher AES-128-CBC
client-cert-not-required
duplicate-cn
verb 3
script-security 3
keepalive 10 60
user nobody
group nogroup
persist-tun
dev-type tun
